The AirTAC Airtac SC40 Standard Cylinder SC40X80TC is a genuine double-acting standard air cylinder with a Ø40mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X80TC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at the 0.9 MPa maximum operating pressure). Its 40 mm bore and 80 mm stroke suit medium-force clamping, pressing, and actuation tasks where a compact tie-rod body is preferred.
This model is factory-configured with a TC centre trunnion mount (supplied with the TCM1 bracket, order code F-SC40TC), allowing the cylinder to pivot during operation. The 16 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration, while the PT1/4 port accepts standard pneumatic fittings.

The 80 mm stroke and pivoting TC mount allow the SC40X80TC to swing a diverter gate on a packaging or sorting conveyor, reliably redirecting products with 628 N of push force at standard line pressure.
Delivers consistent clamping force for medium-duty welding jigs. The adjustable cushion protects the fixture from impact, and the trunnion mount lets the cylinder body self-align as the clamp arm closes.
Operates quarter-turn ball or butterfly valves requiring a pivoting actuator. The 40 mm bore provides ample torque margin at 0.7 MPa, and the PT1/4 ports integrate easily with solenoid valve manifolds.
For applications needing more force, the SC50 series steps up to 982 N push at 0.5 MPa; for a lighter, more compact solution, the SC32 offers 402 N. The centre trunnion mount makes this cylinder ideal for swinging loads—ensure the pivot axis is aligned and the trunnion bolts are sized for the full thrust load.
When replacing an existing cylinder, match five points: 40 mm bore, 80 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting, and the standard TPU seal. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. These values are based on the 40 mm bore and 16 mm rod diameter.
No. The SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder (body length A is 142 mm for the SC40). It is not dimensionally interchangeable with ISO 15552 profile cylinders. It is a direct replacement for another AirTAC SC40 tie-rod cylinder matching the stroke, port, and TC mount.
